Description

Technical Field

[0001] The present application relates to the technical field of bottle caps, and in particular to a bottle cap with a built-in cavity. Background Art

[0002] Food or non-food products in powder or liquid form are very common in current life. These products must be stored and prepared under strict hygiene and safety conditions.

[0003] For the convenience of people's use, powder and liquid products are generally packaged separately. Containers are used to hold liquids, and bottle caps are threadedly connected to the containers and used to seal the container openings. The bottle caps are also used to hold powders or liquids, and when needed, the products in the bottle caps are added to the containers for use.

[0004] A sealing film for blocking the products is provided inside the bottle cap. When in use, the bottle cap needs to be unscrewed and the sealing film needs to be damaged before pouring the products in the bottle cap into the container. Breaking the sealing film is troublesome and tools are required. At the same time, opening the bottle cap easily causes the container to tip over and the liquid in the container to flow out, making the use process extremely troublesome. Moreover, using tools to break the sealing film easily contaminates the products in the bottle cap, reducing the hygiene condition during drinking. Summary of the Invention

[0005] In order to improve the convenience during use and the hygiene condition during drinking, the present application provides a bottle cap with a built-in cavity.

[0006] The bottle cap with a built-in cavity provided by the present application adopts the following technical solutions: A bottle cap with a built-in cavity includes a cap body, a receiving ring, and a blocking device. A receiving cavity is provided inside the cap body. The receiving ring is arranged in the receiving cavity and cooperates with the receiving cavity to form a placement chamber for placing products. The blocking device is arranged on the cap body and used to block the placement chamber. The blocking device includes: An installation pipe, threadedly connected to the receiving cavity and having a threaded section on its inner sidewall for threaded connection with the neck of the container; A blocking mechanism, arranged on the installation pipe and used to block the placement chamber. When mixing is required, the blocking mechanism is opened, and the products in the placement chamber move into the container under the action of gravity for mixing.

[0007] By adopting the above technical solution, during production, the opening of the placement chamber is placed upward, and then products such as liquid or powder are added into the placement chamber. The blocking mechanism is activated to block the opening of the placement chamber, so as to obtain the cap product for standby. Then, the neck of the container is threadedly connected to the installation pipe for positioning. When mixing is required, the blocking mechanism is activated to open the opening of the placement chamber. The product located in the placement chamber moves into the container under the action of gravity and is mixed with the liquid. At the same time, the container can also be shaken to make the two products fully mixed and dissolved, and then it can be drunk. Therefore, there is no need to remove the cap for mixing, which improves the convenience during mixing and also reduces the risk of product contamination, thereby improving the convenience during use and the hygiene condition during drinking at the same time.

[0008] Optionally, the blocking mechanism includes: Two blocking plates, rotatably installed on the installation pipe through a rotating shaft; Two positioning members, arranged on the installation pipe and having elasticity. In the initial state, the two positioning members are inserted and installed on the two blocking plates for positioning and make the two blocking plates cooperate to block the placement chamber; A pushing component, arranged on the installation pipe and used to push the two blocking plates to rotate and open the placement chamber.

[0009] By adopting the above technical solution, when making the cap, the opening end of the placement chamber is upward, and then the product is added into the placement chamber. The two blocking plates are pushed to rotate to block the opening of the placement chamber, and the two blocking plates rotate and squeeze the two positioning members. The two positioning members are inserted and installed on the two blocking plates under the action of elastic force for positioning, so as to complete the production of the cap; The cap is threadedly connected to the neck of the container. When mixing is required, the pushing component is activated to push the two blocking plates to rotate and squeeze the positioning members, so that the two blocking plates rotate to open the opening of the placement chamber. The product located in the placement chamber moves into the container under the action of gravity for mixing, thus greatly improving the convenience during use and the hygiene condition during drinking.

[0010] Optionally, a first groove and a second groove are axially and radially formed on the installation pipe. The first groove and the second groove communicate at one end far from the placement chamber. The pushing component includes: Two pushing blocks, respectively arranged on the side walls of the two blocking plates far from the placement chamber; A support block, slidably installed in the first groove or the second groove. When the support block is located in the first groove, the outer side wall of the container abuts against the support block for positioning and makes the neck of the container keep a certain distance from the two pushing blocks; When mixing is required, push the support block to the connection of the first groove and the second groove, and the container can continue to rotate to push the support block to move in the second groove and make the neck of the container push the two pushing blocks to rotate and make the two blocking plates open the placement chamber.

[0011] By adopting the above technical solution, when installing the bottle cap, the support block is slidably installed on the first groove, and the bottle cap is threadedly connected to the neck of the container, so that the container presses against the support block for positioning, thereby positioning the support block and the container; when mixing is required, the container is first screwed away from the support block, and then the support block is pushed to the connection between the first groove and the second groove, and the container is screwed so that the container and the neck move. The container pushes the support block to move on the second groove, and the neck approaches the push block to drive the push block to rotate, so that the blocking plate rotates to open the placement chamber, thereby realizing the mixing of the two products. Moreover, the blocking plate is opened to the placement chamber by rotating the container, thereby improving the convenience when opening, and the neck approaches the placement chamber to open the blocking plate, so that the neck is as close as possible to the placement chamber, so that the product located in the placement chamber can be better mixed with the product in the container, thereby greatly improving the convenience in use and the hygienic condition when drinking.

[0012] Optionally, the two ends of the blocking plate far from the rotating shaft are positioned by a positioning assembly, and the positioning assembly includes: A snap column and a snap plate, which are respectively arranged on the two blocking plates and are snap-connected to each other for positioning; A limiting member, which is arranged on the snap plate and is used for positioning the position of the snap column under the action of elastic force.

[0013] By adopting the above technical solution, the blocking plate is positioned only by the positioning member, and due to the extrusion of the product, the stability of the blocking plate is poor, so there is a risk that the blocking plate opens the placement chamber in advance and the product overflows.

[0014] When the two blocking plates rotate to block the placement chamber, the snap column presses the limiting member and then is snap-connected to the snap plate, and then the limiting member presses against the snap column under the action of elastic force for positioning, so as to prevent the snap column from separating from the snap plate. At the same time, the positioning member is inserted and installed on the blocking plate, so that the two ends of the blocking plate can be positioned, so the blocking effect of the blocking plate on the placement chamber is greatly improved, so that the two products can be better mixed according to the required requirements, and the convenience in use is improved.

[0015] Optionally, the limiting member is a telescopic member arranged on the snap plate, and the telescopic member expands under the gravity of the product located in the placement chamber and presses against the snap column for positioning and can prevent the product from entering the gap between the snap column and the snap plate.

[0016] By adopting the above technical solution, when an article is added to the placement chamber and then the sealing plate rotates for sealing, the buckling column squeezes the telescopic member and then buckles with the buckling plate. After the telescopic member retracts, it presses against the buckling column for positioning. Then, after the bottle cap is threadedly connected to the neck of the container, the article presses against the telescopic member under the action of gravity. After the telescopic member is compressed, it is used to block the article from entering the gap between the buckling column and the buckling plate, and at the same time, it also presses against the buckling column for positioning. Therefore, the sealing effect of the sealing plate on the placement chamber is greatly improved, enabling better mixing of the two articles according to the required requirements and improving the convenience during use.

[0017] Optionally, elastic plug-in members for positioning by mutual plugging are provided on the side walls of the two sealing plates that abut against each other.

[0018] By adopting the above technical solution, the plug-in members are plug-in mounted on the sealing plates for positioning, so that the two ends of the sealing plate can be positioned, thus greatly improving the sealing effect of the sealing plate on the placement chamber, enabling better mixing of the two articles according to the required requirements, and improving the convenience during use.

[0019] Optionally, a sealing ring for abutting against the receiving ring for sealing is provided on the sealing plate.

[0020] By adopting the above technical solution, the sealing effect is further improved, enabling better mixing of the two articles according to the required requirements and improving the convenience during use.

[0021] Optionally, the pushing assembly includes: Two toggle rods, which are slidably arranged on the mounting pipe along the direction of approaching or departing from the sealing plate and extend to the side of the mounting pipe close to the container; Two plug-in blocks, which are respectively arranged on the two toggle rods, and the two positioning members are respectively arranged on the two plug-in blocks.

[0022] By adopting the above technical solution, the two toggle rods are toggled simultaneously to push the two plug-in blocks to move, so that the two positioning members move away from the sealing plate, and the positioning members are disengaged from the sealing plate, thereby realizing the rotation of the sealing plate to open the placement chamber. When sealing the placement chamber, the two toggle rods are pushed simultaneously to push the two positioning members to be respectively plug-in mounted on the two sealing plates for positioning, so as to complete the mixing of the two articles according to the requirements.

[0023] Optionally, the toggle rod is provided with a toggle piece for facilitating toggling.

[0024] By adopting the above technical solution, it is convenient to better push the toggle rod.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the product is added to the placement chamber, the sealing mechanism is activated to seal the opening of the placement chamber. Then, the neck of the container is threadedly connected to the installation pipe for positioning. When mixing is required, the sealing mechanism is activated to open the opening of the placement chamber. The product located in the placement chamber moves into the container under the action of gravity and mixes with the liquid, and then it can be drunk. Therefore, there is no need to remove the bottle cap for mixing, which improves the convenience during mixing and also reduces the risk of the product being contaminated, thus improving the convenience during use and the hygiene condition during drinking at the same time. 2. By slidably mounting the support block on the first groove body and threadedly connecting the bottle cap to the neck of the container, the container is pressed against the support block for positioning, thereby positioning the support block and the container. When mixing is required, the support block is pushed to the connection of the first groove body and the second groove body, and the container is twisted to push the support block to move on the second groove body, and the neck causes the sealing plate to rotate and open the placement chamber, thus realizing the mixing of the two products. Moreover, by rotating the container, the sealing plate is opened to open the placement chamber, thereby improving the convenience during opening. And the neck is close to the placement chamber to open the sealing plate, making the neck as close as possible to the placement chamber, so that the product located in the placement chamber can better mix with the product in the container, thus greatly improving the convenience during use and the hygiene condition during drinking.

At the same time, when the supporting block 42 is slidably installed on the first groove 25, the supporting block 42 extends radially along the mounting tube 21 to the side of the mounting tube 21 away from the cover body 1, the neck 15 is threadedly connected to the mounting tube 21, and the container 14 is positioned against the end of the supporting block 42 away from the first groove 25, and the neck 15 maintains a certain distance from the two pushing blocks 41.

[0036] Twist the container 14 away from the support block 42, then rotate the support block 42 to move to the connection between the first trough body 25 and the second trough body 26, continue to rotate the container 14 and the neck 15 close to the placement chamber 13, the container 14 pushes the support block 42 to move on the second trough body 26, the neck 15 moves and pushes the two push blocks 41 to rotate, the two push blocks 41 rotate and drive the two blocking plates 31 away from the mounting tube 21, thereby opening the placement chamber 13 and allowing the product located therein to flow into the container 14 for mixing.

[0037] Referring to Figure 2 and Figure 5 , one end of the two plugging plates 31 away from the rotating shaft 23 is positioned by a positioning assembly 5. The positioning assembly 5 includes a buckling column 51, a buckling plate 52, and a limiting member 53. The buckling column 51 and the buckling plate 52 are respectively fixedly installed on the side walls of the two opposite sides of the two plugging plates 31 and are located above the plugging plates 31. A cylindrical buckling groove 54 is formed on the buckling plate 52, and the buckling column 51 and the buckling groove 54 are buckled with each other for positioning; the limiting member 53 is arranged on the buckling plate 52 and is used for positioning the buckling column 51 under the action of elastic force.

[0038] The limiting member 53 is a telescopic member fixedly installed on the buckling plate 52. The telescopic member is a telescopic airbag-like structure. The telescopic member expands under the gravity of the product in the placement chamber 13, and after expansion, it presses against the buckling column 51 for positioning. At the same time, after the telescopic member expands, it blocks the product from entering the gap between the buckling column 51 and the buckling plate 52. Elastic plug-in members 16 that are plugged into each other for positioning are fixedly installed on the side walls of the two plugging plates 31 that are in contact with each other. The plug-in members 16 can be elastic plug-in columns.

[0039] Referring to Figures 1-5 , when the product needs to be placed in the placement chamber 13, the placement chamber 13 is placed with the opening facing upward. At this time, the two plugging plates 31 are in a state of opening the placement chamber 13.

After the limiting member 53 expands, it presses against the buckling column 51 for positioning. When the installation pipe 21 is threadedly connected to the neck 15 of the container 14, the product in the placement chamber 13 will increase the extrusion of the limiting member 53 under the action of gravity, thereby increasing the positioning effect on the buckling column 51 and the buckling plate 52.

[0040] When mixing is required, the neck 15 of the container 14 pushes the two pushing blocks 41, causing the two plugging plates 31 to rotate, so that the buckling column 51 and the buckling plate 52 are separated from each other, thereby opening the placement chamber 13, enabling the product in the placement chamber 13 to move into the container 14 for mixing, so that mixing can be carried out according to the required requirements, improving the convenience during use.

[0041] The working principle of the embodiment of the present application is as follows: When it is necessary to place the product into the placement chamber 13, the placement chamber 13 is placed with the opening facing upwards. At this time, the two sealing plates 31 are in the state of opening the placement chamber 13. The product is added into the placement chamber 13, and the two sealing plates 31 are pushed against the containing ring 11 for sealing. The two positioning members 32 are respectively inserted and installed on the two sealing plates 31 for positioning. At the same time, the snap-fitting column 51 and the snap-fitting plate 52 are snap-fitted with each other. After the limiting member 53 is squeezed and expanded by the product, it is pressed against the snap-fitting column 51 for positioning, thereby improving the sealing effect on the product.

[0042] The support block 42 is pushed to be slidably installed on the first slot body 25, and the mounting tube 21 is threadedly connected to the neck 15 of the container 14, so that the container 14 is pressed against the support block 42 for positioning. At this time, a certain distance is formed between the neck 15 of the container 14 and the blocking plate 31; when mixing is required, the cover body 1 is twisted to disengage the container 14 from the support block 42, and the support block 42 is pushed to slide to the connection between the first slot body 25 and the second slot body 26, and the cover body 1 is twisted to make the container 14 close to the support block 42 and the neck 15 close to the pushing block 41. The container 14 pushes the support block 42 to move on the second slot body 26, and the neck 15 moves to push the pushing block 41 and drive the two blocking plates 31 to rotate, so that the buckle column 51 and the buckle plate 52 are disengaged from each other, thereby opening the placement chamber 13, so that the product located in the placement chamber 13 is moved to the container 14 for mixing, so that it can be mixed according to the required requirements, which improves the convenience during use, reduces the risk of product contamination, and improves the convenience and hygienic conditions during use.

[0044] The working principle of the embodiment of the present application is as follows: When mixing is required, two paddles are toggled to drive two toggling rods 61 and two plug-in blocks 62 to move, so that two positioning members 32 move away from two sealing plates 31, and the products located in the placement chamber 13 move into the container 14 under the action of gravity for mixing. When plugging is required, two sealing plates 31 are pushed close to the placement chamber 13 to implement plugging, and then two paddles are pushed to drive two positioning members 32 to be plugged and installed on two sealing plates 31 for positioning.
